uw-imap fix?

I'm just wondering if the security hole in uw-imap is still being worked on or what the time table for the fix is? Or is the solution to just convert to Courier? I have been holding off on converting to maildir, and I have not read all of the forum posts pertaining to this. I thought the uw-imap server was still planning on being fixed. I am running on the release tree, the fix may be in the Edge release or Current releases, is there a time table for rolling those fixes to Release?
